Dq. Nguyen et al., Transcatheter closure of patent foramen ovale for hypoxemia during left ventricular assist device support, J HEART LUN, 18(10), 1999, pp. 1021-1023
A patent foramen ovale with right-to-left shunting was responsible, in part
, for profound hypoxemia in a patient who required mechanical support with
a left ventricular assist device for cardiogenic shock. The patent foramen
ovale was detected with contrast transesophageal echocardiography, and the
defect was closed successfully with a transcatheter septal defect closure d
evice.
